Track work brings overnight CTA changes

Scheduled track work will affect some service on the CTA Red Line into early Sunday, with more work affecting the Red and Blue Lines later Sunday into Monday morning.

The projects will require single-track operation at various points on the lines, so some minor delays should be expected, the CTA said.

From 11 p.m. Saturday until 5 a.m. Sunday on the Red Line, trains in both directions will run on the same track between the Lake and North/Clybourn stops. Riders will board/exit all trains on the 95th-bound platform at the Grand and Chicago stations, and at the 95th-bound side of the platform at the Clark/Division station.

From 11 p.m. Sunday until 4 a.m. Monday on the Red Line, trains will run in both directions on the same track between the Sox-35th and Garfield stops. Riders will board/exit all trains on the Howard-bound side of the platform at 47th Street.

During some times from 10 p.m. Sunday until 4 a.m. Monday on the Blue Line, trains in both directions will run on a single track between Jefferson Park and Rosemont.

From 10 p.m. to midnight riders will board/exit all trains on the Forest Park-bound side of the platform at the Cumberland station, while from midnight until 4 a.m. Monday riders will board/exit all trains on the Forest Park-bound side of the platform at both the Harlem (O'Hare Branch) and Cumberland stations.
